(5 out of 5) M18

Just an awesome weapon....

(5 out of 5) M18 is awesome
by from Boise, ID on

I ordered this on the day it was available. I knew I wanted a P320 but was on the fence on which version to get. I love it, have three other grip modules and multiple mags its like having 4 pistols in one. dead on out of the box. No problems, highly recommend.

(5 out of 5) Perfect Carry Pistol!
by from Terre Haute, IN on

Not sure how I was able to get one of these, but Google search saved the day. Ordered it a day after Sig released an article on it and got it about a week later. So far I have 200 rounds through it and love it. I love that it comes with 3 magazines and is red dot ready out of the box.

(5 out of 5) Great Pistol!
by from Old Forge, PA on

Fantastic running pistol. Had it a week and have run 1k rds through it without any issues. Xray sights are right on. Curved trigger is ok, but I'm sure a SIG flat trigger will make it even better.

I think the Sig Sauer P320 M18 Carry 9mm Optics Ready Pistol, is a fantastic side arm. And I know this may sound petty, but I wish the M18 came with three 17 round magazines instead of the one 17 round and two 21 round magazines or three 21 round magazines. Just for the consistency for Duty carry.
